| Abstract: | The large deflection response of nonlinear thin beam structure to blast load is analyzed by the theory of large deflection elastic beam and central difference method in this paper. The analytical model includes the elastic coupling between transverse and longitudinal deformations. The numerical examples give the effects of the tension-bending coupling,the tension/bending stiffness ratio and the blast impulse on the deflection response of beams. |
